Answer:
7x+12
Step-by-step explanation:
You do 10x-3x since they both have the x variable they can be combined to make 7x and the 12 is left alone.
Answer:
x = 76°
Step-by-step explanation:
At point I
to get angle JID
angle JID + 107° = 180°. (angle on a straight line)
angle JID = 180° - 107°
angle JID = 73°
for Triangle JiD
angle DJI + 31° + 73° = 180° (Sum of angles in a triangle)
angle DJI = 180 - 104 = 76°
angle FJI = 31 + 73 =104°. ( Sum of two interior angles in a triangle is equal to one exterior angle)
Hence,
x° + 104° = 180° (angle on a straight line)
x = 76°
Answer:
1,025 divided by 25 = 41
Step-by-step explanation:
Answer:
20
Step-by-step explanation:
its a pattern. the top goes up by three's so if it goes from 12 to 30 the d8 should go to 20 because if you add 3 to 12 to get it higher than you add 2 to 8 to get it higher.
